wordpress - 当我发布新帖子时(而不是当我更新已发布的帖子时)，wordpress Hook 是什么？

Question

我想在新帖子首次发布时(而不是编辑时)发送电子邮件

我尝试过:

add_action('publish_post', 'postPublished');

但是 postPublished 当我更新已发布的帖子时也会调用。我只想仅在第一次发布帖子时将其称为。

我认为您正在寻找的钩子(Hook)是draft_to_publish

如果您只想在新帖子上发送电子邮件，我会考虑在帖子发布时进行定位。您甚至可以查看transition_post_status Hook 并只是条件化帖子是否已被编辑，这样的事情可以工作:

function so_post_40744782( $new_status, $old_status, $post ) {
    if ( $new_status == 'publish' && $old_status != 'publish' ) {
        $author = "foobar";
        $message = "We wanted to notify you a new post has been published.";
        wp_mail($author, "New Post Published", $message);
    }
}
add_action('transition_post_status', 'so_post_40744782', 10, 3 );
